LIGHTER.

Application nled June 8,

To all whom it may concern:

Be it known that I, MILTON H. SHOENBERG, a citizen of the United States, and resident of the city and county of San Francisco, State of California, have invented new and useful Improvements in Lighters, of which the following is a specification.

My invention has for its ob'ect a portable device adapted to be energize kvby electricity for the purpose of lighting cigars, cigarettes or the like. The device consists of a casing and an insulated base within which are arranged a. switch and a heating coil and terminal connections to which a cord to supply energizin current may be attached.

Other o jects will appear from the drawings and specifications.

By referring to the drawings my invcntion will be madeclear.

Fig. l is a front view of my lighter.

Fi 2 is a cross section of Fig. 1 on the line lI-II thereof.

Fig. 3 is a front view with the heating coil and insulated cover and guard ring removed to show the recess in the base or casing, and on which are shown by dotted lines the relative position of the heating coil and its terminals and the wire connections there- Fi 4 is a cross section of Fig. 1 on the line V-IV thereof.

Fig. 5 is a perspective view of the switch blade.

Throughout the figures similar numerals refer to identical parts.

A base member formed of rubber, bakelite, plaster or other suitable material and preferably of insulation material is shown y the numeral 1, although ametallic casing with an insulated lining may be employed in lieu thereof, if preferred. At 2 1s shown acover plate of mica or other insulation and mounted thereon a helical resistance coil 3 of resistance wire and which latter is adapted'to be heated by the flow of electric current across the terminals 4, 5. A guard ring 6 surrounds the ex sed heated parts, having a sui-table opening therein to admit of a cigar or cigarette being passed therethrou h and against the helical wire 3, theheat o? which when energized, lightino' the cigar. The terminals 4, 5, extend 1922. Serial No. 566,830.

through the plate 2 and are provided with lock nuts 7, 8, which securely hold the helical coil to the insulated cover 2, leaving the said column terminals 4, 5, extending downward as at 9, 10, until they contact with and are supported from the bottom or floor 11 of the recess 13 in the casing 1. A hook or other suitable means by Which the lighter may be suspended is indicated at 14 and fastening rivets or screws for the ring 6 are shown at 15, 16. The electric cord connections 17, 18, convey energizing current for the resistance coil 3; 17 being attached to the terminal 10 and 18 vbeing soldered to the switch member 19. This latter is formed with a spring tension by which it normally occupies the full line position of Fig. 3 bearing against the` push button 2O and normally in its extended position of Figs. 1, 2, 3. When the said push button is depressed into the position 21, the spring 19 is shifted into its dotted position in contact at such time vwith the column terminal 9 of the coil 3,thus completing a circuit from 18 through 19, 9, 3, 10, back to connection 17 and energizing the helical coil 3 which now becomes sufficiently heated to light the cigar, cigarette or other article which it is desired to fire. The inner periphery of the recess 13 forms a bearing surface on which the projecting portion 22 of the spring 19 bears when the spring is actuated from the full line to the dotted position of Fig. 3. The

.recess at 23 is for retaining the cover 2 and the ring 6 flush with the surface of the casing 1 when the parts are assembled at which time the terminals 9, 10, bearing upon the surface 11 firmly support the central portions of the cover 2 and helical coil 3 so that the parts will not be distorted when the cigar is pressed against the incandescent coil. The helical coil is made with a straight line axis and of relatively coarse resistance wire so that it is not normally subject to easy breakage or disruption and when utilizing six or twelve volts corresponding with the storage battery or current generated in most automobiles, very quickly comes to the incandescent point with an expenditure 0f approximatel 1% amperes and it is therefore well suited without undue strain upon the battery for service in an ausoy tomobile. The proportions or" the helix to give the desired results are preierabiy made substantially as shown where its len "i is substantially eight times its diameter, thus giving great eiiiciency and stability in service.

It will be seen that the cover plate eolumns 9, l0, and helix: 3 torni a unitary structure easily replaceable under the ring 6 and in casing l, should the helix at anyv time become damaged.
